November 2017

Design Of Experiments (DOE) is all about the set up and overall testing strategy. This link provides a one hour webinar with these basics of DOE. If you want more so you can run basic experiments yourself, you can sign up for the self-paced course, which will be available soon. It does not require special software beyond Excel to start simple tests, with limited analysis. Contact us for more information or for help on your more complicated and important projects. Over 30 years of experience and hundreds of projects in both manufacturing and design applications support this content.

The next core area to discuss with a training program is Analyze. The ability to examine test data using key diagnostics and create an unbiased decision is critical for engineering performance. It is easy to do but overlooked too often. Smart and complete analysis provides key learning points beyond the obvious "model building" desired from Design of Experiments. We provide an analysis Cheat Sheet with our DOE training. Our other classes provide similar tools to assist with retaining key points.

In the fall I created an article about experimentation for MD+DI magazine. This provides the basics of creating a successful experiment with examples. The MDM talk on November 9 expanded on these thoughts to connect with specific FDA expectations. It is good solid engineering and new product development habits for any industry. Call us to avoid bad experiments, reduce scrap and finish projects on time.

Videos and video briefs

Each brief has 3 videos to expand on various areas for each topic. Pick an area of interest and improve your understanding.

Manufacturing Projects How do we approach a manufacturing project - to address it permanently yet with limited scrap and downtime.

Achieving Innovation Companies want to be creative and innovative. How can Design of Experiments help with that? You might be surprised.

Overcoming Development Challenges When a project experiences a challenge, what do you do? What should you do? We explore this topic - a key to successful New Product Development.

Project Execution Are the projects executed valuable? Here are case studies at various phases of the process.

Program Management How can effectiveness be improved with New Product Development? What are keys to success.

Underused Product Development Tools When involved in new product development, we have no time for wasting time. What tools should we be interested in?

Training Effectiveness How do we create a valuable training program? How can we spot a bad one?

Our DOE Process - Decision Making Focus Too often Design of Experiments is presented as a series of tools. Instead, it is best used as a decision making methodology.

Achieving Robust Design Creating a Robust Design is of high interest. How can you make it happen? Can you do it cost effectively? We can provide a design or process that meets the level of robustness that you desire and maintain your schedule.
